FPC: got RX working, got client over usart somehow working..., see detailed commit msg * using WITH_FPC: * activate basic usart * no double buffer for now, no interrupt * usart_dataavailable/usart_readbuffer/usart_writebuffer, to demo it: * pm3 client over USB, minicom over usart * analyse a d 414243 * using WITH_FPC_HOST: * it implies WITH_FPC as it's based on it * control pm3 with client over usart * EXPERIMENTAL! still some frame desync issues * you can connect both from usart & USB with two pm3 clients * actually you have to connect USB for the moment because it's used to send debug messages about buggy usart... See Dbprintf_usb below * "sessions": msgs are directed to the latest client to have sent a cmd * Dbprintf_usb macro to send msgs to USB client to help debugging usart... * We now have an option to run client at different speed as usart is 115200: client/proxmark3 /dev/ttyUSB0 -b 115200 * Consequently, argc,argv handling is a bit revamped, it was so messy... * USB and flashing are still at 460800, don't try flashing over usart yet ^^ 2019-04-03 04:06:10 +08:00			`int16_t usart_readbuffer(uint8_t *data);`
CHG: the thread comms refactoring from offical pm3 repo chg: FPC com speed limited to 115200 when compiled with FPC chg: USART remake (@drandreas) 2018-09-07 03:43:20 +08:00			`int16_t usart_writebuffer(uint8_t *data, size_t len);`
FPC experiments: got so far TX_only, usart=115200 + usb=460800, see full commit msg * Add \r\n to sent strings * remove usart_init() from UsbPacketReceive cmd, it's already init in main. * Add PLATFORM PM3RDV4FPC to ease dev * TX: US_TCR is len of data to send, not len of buffer * Use only one PDC bank as we're using it in sync * Busy loop to wait for end of TX as we'using it in sync * Change usart speed to 115200 * Don't downgrade USB speed, keep 460800 * Attempt to detect received data, fail so far 2019-04-02 07:06:00 +08:00			`bool usart_dataavailable(void);`
